As stated, just back off of max charge a little+will work fine. Hell, I have been using Small Rifle primers in some small pistol loads for awhile. I found some Rem. 61/2 primers at a deal. They are about the same power as Mag pistol primers, I have been told. Seem to work fine. I'll be glad when pistol primers become available again.

Yeah, been using Magnum CCI primers for years and haven't had any problems with them. I just drop the load on 231 Winchester powder or Bullseye for about 1/2 to 1 grain when I'm reloading 230 lead round nose on .45 ACPs. I haven't used Large pistol primers for years now.
